What does electro negativity value depend on ?

Emission: n=3 to n=2 and n=2 to n=1; absorption: n=1 to n=3 and n=3 to n=5.

The process that absorbs a photon and puts the atom or molecule in an excited state is called absorption. The process of emission involves producing a photon and returning an excited atom or molecule to its ground state.

While absorption strains speak to the propensity of cold ambient fuel to absorb the same lines of mild, emission strains seek guidance from the reality that sparkling warm gasoline emits strains of mild. In the presence of gas in the environment, some light at specific wavelengths is scattered, resulting in darker bands.

By measuring the frequency of each orbital, it is possible to determine the electrical difference between them.

radiation. Light emission and absorption can reveal a lot about the atomic structure. While the light that is emitted is mild and visible, the light that is absorbed is light that isn't always apparent. Electrons emit as they return to higher electrical levels.

Answer:

2.677 J/g°C

Explanation:

Quantity of heat required to raise the temperature of the metal,

Q = mc∆T

where m is the mass of the metal, c is the metal's specific heat capacity, and ∆T is the change in temperature that accompanies the heat transfer process

20.0J = 50.0g × c × 150°C

c = 20.0J/(50.0g × 150°C)

c = 2.677 J/g°C

Answer:

\(\boxed {\boxed {\sf 3.1 \ liters}}\)

Explanation:

This question asks us to find the new volume if the pressure changes. Therefore, we use Boyle's Law, which states that pressure and the volume of the gas are inversely proportional. The formula is:

\(P_1V_1=P_2V_2\)

We know that the original sample of gas occupies 4.5 liters at a pressure of 1.63 atmospheres.  We know that the pressure was changed to 2.4 atmospheres, but we don't know the volume. Substitute all known values into the formula.

\(4.5 \ L * 1.63 \ atm= 2.4 \ atm * V_2\)

Since we are solving for the new volume (V₂), we need to isolate the variable. It is being multiplied by 2.4 atmospheres and the inverse of multiplication is division. Divide both sides by 2.4 atm.

\(\frac {4.5 \ L * 1.63 \ atm}{2.4 \ atm}= \frac{2.4 \ atm * V_2}{2.4 \ atm}\)

\(\frac {4.5 \ L * 1.63 \ atm}{2.4 \ atm}= V_2\)

The units of atmospheres (atm) cancel.

\(\frac {4.5 \ L * 1.63 }{2.4 }=V_2\)

\(\frac {7.335 \ L}{2.4 }=V_2\)

\(3.05625 \ L= V_2\)

The smallest number of significant figures in the original measurements is 2, so our answer must have the same. For the number we found, that is the tenths place.

The 5 in the hundredth place tells us to round the 0 up to a 1.

\(3.1 \ L = V_2\)

The volume of the neon gas when the pressure is changed to 2.4 atmospheres is 3.1 Liters.

Explanation:

\(P1V1 = P2V2\)

\(P1=1.63atm

\\ V1=4.5 L

\\ P2=2.4 atm

\\ V2=?\)

\(V2 = \frac{1.63 \times 4.5}{2.4} \)

\(V2 = 3.05625 \: Litres\)

The melting point obtained for your product, The sample  3-nitroaniline appear to be a mixture.

If the range of experimental melting point varies greatly (more than 5oC) from the literature range then the substance is considered to be impure else it is more or less said to be pure

The three-nitroaniline is a natural base; there may be a lone pair of electrons at the nitrogen atom of the amino institution, making 3-nitroaniline a Lewis base (an electron pair donor). below these situations, biphenyl has neither an acidic proton nor a lone pair of electrons to donate and is taken into consideration a neutral compound.

Three-Nitroaniline, also known as meta-nitroaniline and m-nitroaniline, is a non-risky strong solid commonly used as a raw fabric for dyes. Here the range does not differ so much so 3-nitroaniline is pure.

The mass of butane in the mixture is 0.3899 kg.

Given: The gas mixture has a molar composition of 17% methane, 39% butane and the remainder is ethane. The gas mixture is inside a 0.5 m³ closed vessel at 2.3 bar, 60°C.Molar mass of methane (CH₄) = 16 g/molMolar mass of butane (C₄H₁₀) = 58 g/mol Molar mass of ethane

(C₂H₆) = 30 g/mol Using the ideal gas equation for n (number of moles) and substituting the values,

PV = nRT Where

P = 2.3 bar,

V = 0.5 m³,

R = 0.0831 L bar/mol K,

T = (60 + 273.15) K

= 333.15 K.

Therefore, n = PV/RT

= (2.3 × 10⁵ Pa × 0.5 m³)/(8.31 J/mol K × 333.15 K)

= 0.035 mol Moles of butane

= 0.17 × 0.035

= 0.00595 mol Moles of ethane

= (1 - 0.17 - 0.39) × 0.035
= 0.01135 mol Moles of butane in 1 kg of gas mixture

= (1000 g)/(58 g/mol) × 0.39

= 6.7241 mol Butane has a molecular weight of 58 g/mol, which implies that the mass of butane is given by mass

= number of moles × molecular weight

Answer: Point north.

The mass of platinum present in a 37g sample of this compound is calculated to be 27.136 g

To determine the mass of platinum we first determine the empirical formula as follows;

chlorine: mass / molar mass = 2.30 / 35.453 = 0.065 moles

platinum: mass / molar mass = 6.33 / 195.084 = 0.032 moles

Now dividing each of the calculated mole values by the smallest number of moles;

chlorine: 0.065 / 0.032 = 2.03 ≈ 2

platinum : 0.032 / 0.032 = 1

Therefore the empirical formula would be \(PtCl_{2}\)

Now we have to find the mass of platinum in 37g of \(PtCl_{2}\);

mass of platinum / total mass = x / 37

x / 37 = ( 195.084)/(195.084 + 2×35.454)

x / 37 = 0.73342

x = 37 × 0.73342

x = 27.136

Hence the mass of platinum in a 37g sample of this compound is calculated to be 27.136 g

The overall change in entropy for the process is approximately -0.251 J/K.

The change in entropy can be calculated using the formula:

ΔS = nCp ln(T2/T1) + nR ln(V2/V1)

where:

n = 0.13 moles (number of moles of helium in the balloon)

Cp = 5/2R (specific heat capacity of helium gas at constant pressure)

R = 8.314 J/(mol*K) (gas constant)

T1 = 298 K (initial temperature of the helium gas)

T2 = 291 K (final temperature of the helium gas)

V1 = 3.0 L (initial volume of the balloon)

V2 = 3.5 L (final volume of the balloon)

Plugging in the values, we get:

ΔS = (0.13 mol * 5/2 * 8.314 J/(molK)) ln(291 K/298 K) + (0.13 mol * 8.314 J/(molK)) ln(3.5 L/3.0 L)

ΔS = -0.296 J/K + 0.045 J/K

ΔS = -0.251 J/K

Therefore, the overall change in entropy for the process is approximately -0.251 J/K.

The statement "molecules move in random directions when heated in a heat engine, and because of the lack of uniformity in the direction of molecular movement" is true.

When a heat engine is heated, molecules absorb heat energy and their kinetic energy increases. The kinetic energy of molecules causes them to move around. However, this movement is not uniform, and the molecules move in random directions.

A heat engine is a device that converts thermal energy into mechanical energy. Heat engines operate on the principle of thermodynamics.

They work by taking in thermal energy from a high-temperature reservoir, converting some of it into mechanical energy, and then releasing the remaining thermal energy to a low-temperature reservoir.The internal combustion engine in a car, the steam engine in an old locomotive, and the turbine in a power plant are all examples of heat engines.

It is a multisubunit enzyme that contains many functional regions that are critical for the synthesis of RNA from a DNA template.The RNA polymerase of E. coli is a complex enzyme that has a number of important properties. The RNA polymerase is composed of five different subunits that are arranged in a holoenzyme configuration.

This holoenzyme is responsible for the recognition of promoter sequences on the DNA template and the subsequent initiation of RNA synthesis. RNA polymerase from E. coli reads the DNA template from its 3' end to its 5' end during RNA synthesis. This is in contrast to DNA polymerase, which reads the DNA template from its 5' end to its 3' end during DNA replication.

RNA polymerase from E. coli uses a single strand of dsDNA to direct RNA synthesis. The enzyme recognizes the template strand and reads it in the 3' to 5' direction, synthesizing the RNA strand in the 5' to 3' direction. This process is called transcription.
